Sistema Sac Actun has been connected to Sistema Nohoch Nah Chich, creating a system 154,783 meters long, the longest underwater cave in the world! That beats the previous record of 146,761 meters for Ox Bel Ha. The two longest caves in Mexico are now almost entirely underwater. Read all about it at http://www.caves.org/project/qrss/new.htm(The underwater portion of Sac Actun is 152,975 m long, but there are also 1808 m of dry cave, thus the longer total. See http://www.caves.org/project/qrss/qrdry.htm).

A few years ago I had to do a cave sketch in "feet" because that particular project used "feet" instead of "meters" and I practically couldn't do it. My mind only worked in meters for sketching. But when it comes to long numbers like that with reference to distance, I'm used to the odometer in my car and miles makes more sense to me. As is does to AMERICANS here in the NSS based in ALABAMA, US and A!!!!!
